Unfortunately, they don't seem to have this on their web archive yet, but
They had two units. Both were battery operated completely electric, and
looked to run off 12v. The smaller one had a single blade (I think it was
12"), the large had three small blades (that actually looked like food
processor blades). The blades are sunk into the body for safety to avoid
The smaller unit was actually more expensive because it would home in on
it's charger and recharge itself when needed, the larger one needed to be
manually recharged. Both used a random pattern, with a buried wire to keep
it in bounds.
What was interesting was that larger unit was less than $500. I would think
that, for the safety reasons, anyone looking to work on methods for a robot
mower would be better of starting with one of these as the base.
Now, hopefully they add this to the site soon, as I don't recall the
companies at all.
